My husband and I need assistance on the best method to prepare drywall patches for painting. We are finishing off our 3rd floor attic and the majority of the electrical in the attic had to be re-run to install joists. Because of this the electrician had to make numerous cuts in the walls on the 2nd floor to remove and reinstall the outlets and light switches which were impacted by re-routing the electrical.
The openings have been repaired with the new drywall and are now ready for taping, mudding and sanding. I am planning on using pre-packaged tubs of joint compound for the repairs.
We are concerned that with the number of holes we must paint that the repairs will stand out unless primed properly. Repainting each room seems inevitable but we don't want to end up seeing the repair due to differences in texture and/or paint absorption. All the walls are painted in an eggshell paint by Behr or Sherwin Williams and have been painted in the last 3 years.
So here are our questions:
-Is joint compound the best product to use?
-What type of primer should we use?
-Are there any other steps we can take to prevent the repaired areas from showing?
Thanks for the help!
